Based on my own experience with horrible back pain, I'd say that any book which gets people to explore this fascinating field of self-discovery is to be applauded. (I'd also suggest "Fitness Without Stress - A Guide to the Alexander Technique" and "The Alexander Technique Manual")I'd been constant pain for over ten years before a friend gave me a couple of Alexander books to read and I was finally persuaded to take some lessons. At first I was puzzled by what my teacher was trying to show me, but within a couple of weeks my pain had diminished considerably. That was five years ago and I can honestly say I'm been 98% pain-free since then. I believe the Alexander Technique is one of the most useful things you can investigate if you're in pain.
